POE Combiner Splitter Adapter, Run 2 IP Cameras on 1 Cable, Works on All POE Switches, POE NVR and POE Cameras, Mode A and B POE Compatible

This worked very well for me.. My original cable is about 75ft (23m). After installing the splitters, i extended one PoE camera another 30ft (9m) and both cameras work well.The only thing i did was determine which cable split corresponds to the far end cable split. That was simple by setting up everything next to my PoE switch and just plug one end at a time and see which cable end powered up the camera and i just marked each end with a cable marker.

I bought one about six months ago after researching. Then bought a few more! Was a little unsure with the first one if it would work initially, given the power draw by two devices. But it has a switch for two types of wiring, good just in case! And I used the higher power PoE+ switch that was 802.3AT compliant. PoE switches that are only 802.3AF compliant don't put out nearly as much power on the line. So make sure your PoE switch is 802.3AF (PoE+) compliant. May work with one that's only 802.3AT, but I wouldn't try it to find out unless you already had one there. The better PoE+ switches aren't expensive.I had a PoE wired Ring cam, but wanted to add a Reolink PTZ camera about 15ft from the Ring cam that was also wired PoE without running an entire new cable. Easy to install, and both devices powered up and connected without any issues. Still running without a glitch 4 months later. So if you were going to use it to connect say two Ring or similar PoE cameras, it would have no problem with it as I'm fairly sure the Reolink PTZ cam pulls more power than the Ring cam with it's auto tracking.I wouldn't experiment with cheaper PoE splitters. This one is well engineered and won't let you down.

These have been great. So much more efficient that running an additional wire especially when the access is not convenient. Not sure if it supports gigabit speed but I have not had and issues with 4-5 of these on a system.

It works, but I would have changed a few things... thing 1, the waterproof connectors are junk. I've done plenty of outdoor POE camera installs and there are connectors that work, and connectors that don't. These don't. I always use dielectric grease in the plugs to help with moisture resistance and even though I did that, I had this unit out for one day. One day! And rain came, water got in, and some of the cheap contacts in there rusted out. Probably shorted the POE if I had to guess (no damage to the switch though, a good POE switch knows when that happens and cuts off power).Thing 2, rather than having RJ-45 sockets on the output side, I would have preferred RJ-45 plugs. That's just me, so maybe there should be an option. As it is, for my install I had two cameras right there on a pole, basically facing forward and backward. So to use this, I had to grab a couple short cables to stick in between which just means even more watertight connectors to deal with, etc.When I had my water ingress and rusted pin, I just got done snipping off that particular socket (I think it was camera 1). I tested which color wires went to which pins so I could just wire it up to a new RJ-45 plug, which is currently working okay, and now I've avoided one extra ethernet cable on my setup. However, there's precious little slack on those wires where it splits out, so there's no way I could get a waterproof connector on. I'll have to stick with electrical tape and the aforementioned dielectric grease. Plus it helps to position the connection in a way that gravity will not let water pool into the socket itself.For anyone else who might need to rewire this... I didn't cut off the pigtail going to the 2nd camera, but at least on the first one (and you know which one is #1 because it's using pins 1,2,3 and 6 ... the other one uses 4,5,7,8), the wire colors are: #1 = white, #2 = yellow, #3 = black, and #6 = red. Wire those to an RJ-45 plug and you can do it too.Bear in mind, these wires in there are kind of cheap stranded wires, so good luck pushing it into your RJ-45. I tried and tried... eventually I had to strip back just a little bit of the wire itself and tin it with fresh solder, and that lets you push it into the plug and crimp it. It's also a pain in the neck to wire when you're only dealing with 4... pushing in all 8 wires is pretty easy because you just line them up and go. With 4, and using 1,2,3,6, it's kind of tricky to get it just right, so it takes some time and patience.Now, I figure I could have returned this since it's literally 2 days old and already rusted and broken, but I can't say for sure if the water issue was my fault or the crummy waterproof connector, so I sucked it up and fixed it on my own.For all the other connections, I made sure to use generous electrical tape now on all those joints. I figure water just got in past the rubber grommet where the wire goes in, because it's not really that tight, so taping it there to prevent water from getting there in the first place helps. I've done that in other spots where the connector seemed dubious. Time will tell if it all holds.

I needed to extend a single ethernet line from my front porch camera to the far corner of my home. I needed to add 20 feet of ethernet cable to to reach the new camera. I wired the POE Combiner/Splitter Adapter as instructed by the documentation that accompanied the ethernet splitter. I selected that default "mode A' for my Amcrest setup. The splitter worked as advertised. The combined cameras on the single line have been working flawlessly with no dropped frames. The cameras that I using are five Amcrest IP2M-842EW outdoor bullet cameras. I also have one IP5M-B1186EW Amcrest outdoor bullet camera that I recently purchased. All cameras perform nicely.

Connected this up to two of my I.P cameras on one CAT5 UTP as I did not want to run a second cable back to my POE switch due to the difficulty of running the extra cable.Connected them exactly how the manual instructs you to and initially worked fine.A few hours later one of the cameras kept going off line and I thought the camera was maybe faulty and replaced it.Same problem occurred again, camera would stay on line for a while and then go offline and the only way to solve the issue was a reboot of the POE switch.Also changed the POE switch to a higher wattage unit but made no difference to the problem,cameras would go offline for no reason at random periodsAfter many days of trying different makes and models of I.P cameras and much time and frustration I ran a separate cable for my additional camera and threw this thing out.Would not recommend as this did not work for me at all.
